Where do I add grease (not oil) to an older Necchi sewing machine?
When I repair a machine I use triflow oil on any metal to metal rotating part ie back and forth. On metal gears I put the tri flow grease. You can use it on plastic gears although sparingly. the nylon gears were design for quietness and were not recommended for grease. You want to get the old grease off as best you can. If it goes up and down or side to side then oil. If it continuously rotates then grease. Exception those bearings that have an oil hole vs a grease cap.
